Application filed February 7, 1912.

To all whom t may concern Be it known that we, WiLLIAM H. lNinnnn and FRED E. idliiirn, citizens of the United States, residing at Gardner, lvfassachusetts, have invented certain new and useful lmprovei'nents in Ovens, of which the following is a specification..

Our present invention relates more especially to improvements in portable ovens designed for use in connection with oil and gasolene stoves, and has among others for its objects to provide an oven with a very simple and economical form of shelf and shelf support with a shelf free from projections and permitting free sliding` of the dishes, and capable of being readily inserted and firmly held in position during use.

`With these and other objects in view, the invention includes the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

An oven constructed in accordance with our invention is illustrated in the accompanying drawings in which- Figure l is a transverse vertical section through the oven, and F ig. 2 is a plan view of the bottom shelf.

Referring by reference characters to this drawing the numeral l designates an outer sheet metal case, preferably of rectangular form and having in the bottoni an opening 2 to permit the entrance of the heated gases. rlhe sides, top and back of the outer case are preferably lined with asbestos as indicated at 3, and within the case at the sides, bach, and top is an inner lining of sheet metal indicated at t, the top lining being arched as indicated at da to avoid corners which would tend to retain cold air.

Lower and upper shelves are indicated at 5 and 5a, and these shelves are composed of longitudinal bars a and b respectively, which are connected by and support the transverse rods o upon which the articles Within the oven rest. The transverse bars a and o are formed of strips of sheet metal folded upon themselves, with the ends of the rods o clamped between said folded portions,A the sheet metal being pressed down between the rods as indicated at a and o to hold the rods firmly in position.

Shelves have heretofore usually been supported by ledges or flanges projecting` from the walls of the oven which is objectionable Specification of Letters Patent.

as obstructing the flow of heated air at the sides of the oven and also provides corners for the collection of grease and dirt which are difficult to clean.

Our improved shelf is supported at the back by projecting two or more of the rods c through openings in the back bar .7), as indicated at o2, holes le being provided in the back lining to receive these projected ends. ylhe holes are preferably countersunk as shown by pressing or swaging the metal outward, to facilitate the entrance of the ends of the rods. The front bars a are folde ed into substantially L shape to'provide a downwardly extending iiange a2 which drops into recesses or spaces 03 between the .two projections (Z2 at the front. These projections are formed by inward bends in a vertically disposed strip D secured to the inner case or lining on each side in proximity to the door opening, there being one set of projections for the upper shelf and a corresponding set for the lower shelf. rlhe strips are held in place by having their ends inserted in slits in the inner case or lining and their intermediate portions secured by rivets or like fastening devices.

By the foregoing construction a very simple and economical form of shelf and shelf support is provided, the shelf being free from projections and permitting free sliding of the dishes or other articles thereon due to the rods extending bach from the doorway to the back wall parallel to the line of movement of the dishes., and the shelves are readily insertible and removable and firmly held in position during use.

To the lower shelf we secure a combined drip pan and deiiector 6 which comprises a sheet of metal having upwardly turned ends bent over and around the outside rods of the shelf.

At the front of the oven and closing the front opening thereto we provide a door 7 of sheet metal which is hinged at its lower edge byhinges not shown which support it in a horizontal position when opened outward. rihe door is preferably provided with a handle l12L pivoted at 11 and controlling a locking device 10b, and also with one or more glass panes 14. held at their edges by flanges l5.

Having thus described our invention what we claim is:

l. An oven having recesses in the back wall thereof, and a shelf 'comprising longitudinal cross bars at front and back and transverse rods connecting said cross bars, part of said rods being projected beyond the rear cross bar to enter said recesses.

2. An oven having recesses in its back cesses on its sides near the front and a shelf having at the rear projections to enter said recesses and at each front corner a vertically depending flange to enter the recesses in the lugs.

3. An oven having recesses in its back wall and lugs provided with vertical recesses on its sides near the front, and a shelf comprising front and rear cross bars connected by transverse rods, part of said vrods being'projected beyond the rear cross bar to enter said recesses and said front cross bar having a depending` fiange to enter the recesses of said lugs.

4L. An oven having means carried by the back wall for supporting a shelf, sheet metal strips secured to the inner wall of the oven near the front, said strips having inward bends provided with vvertical slots, and a shelf Ahaving its rear end supported by the back wall of the oven and having at the front a bar with a vertical flange having itsnends seated in said vertical slots. Walland lugs provided with vertical re- -5. An oven having recesses in its back wall and lugs on its sides near the front provided with vertical recesses and a shelf comprising transverse rods and front and rear cross bars comprising strips ofy sheet inetal folded upon itself with the rods clainped between the folded portions, part of the rods being projected beyond the rear cross bar to enter said recesses, said front bar having a depending flange with its ends seated in the recesses in the lugs.

In testimony whereof, we affix our signatures in presence of two witnesses.
